Zeeb Aurora does both breasts at the same time of course. Its a machine designed specifically to do breasts and that is the most efficient way to work. Its in their specification... Again when the antenna receives the Rf signal from water and the system corrects for phase shifting etc then same for the fat...and stores it in memory.. Tumors either register as a different resonant frequency or as voids in either case I think the machine spatial resolution still holds and the accuracy is not adversely affected. The problem you are concerned with rate of gallodinium apsorption is actually not that it takes a long time to absorb but that it occurs relatively fast and wears out in minutes so you need to be expedient during this process.

Zeev, Fonar could do 1 breast at a time too, but wouldn't normally for the reasons you mention. The fonar Quad system is not anything special for brest imaging and can image breasts or anything else, albeit with some limitations. The Fonar thread has lots of enthusiastic supporters of Fonar but much of what they sy is tainted by what they would like to believe, such as "Fonar is great for breast imaging". In fact, Fonar offers nothing over ANY other magnet in the QUAD. I suspect, as I have said, that they are going to announce a dedicated machine for breast, much like the system Warren just posted. THAT machine, and others like it, will be introduced at the RSNA and will give the ANMR system a run for its money. It is obvious tht a cheap machine tht can give good mammo results will be a winner and so I think there will be lots of vendors throwing their technology at it this year. This is all just guessing though.
